摘要： PURPOSE:To compensate a voltage variation together with a waveform distortion and a flicker by interposing, in series with an adding polarity, a compensation power source for always generating a compensating voltage in response to the variation in the voltage of a power source of a system side between the system side power source and a load. CONSTITUTION:A compensation power source 10 for always generating a compensating voltage VH in response to the variation in the voltage VS of a system side power source 1 is interposed in series with an adding polarity between the power source 1 and a load 7. The power source 10 rectifies by a rectifier 2 the power source voltage CVS to charge a capacitor 3 having a large capacity and opens/closes an inverter 4 by a signal responsive to the variation in the voltage VS output from a controller 8, thereby generating a voltage V1. The voltage V1 is applied to the primary side of a coupling transformer 5, the voltage VH is generated from its secondary side, added to the voltage VS as a voltage VL, and applied to the load 7. Thus, the variation in the voltage having large varying width, and the variation in the voltage having a small varying width, such as a waveform distortion, a flicker or the like can be compensated.

摘要： PURPOSE:To enable detection of a momentary voltage drop in real time, by comparing an input with the results obtained by subtracting a instantaneous voltage drop detection level at a peak value point from an input waveform as reference waveform. CONSTITUTION:A PLL circuit 22 receives an input voltage vS and feeds an output thereof as synchronous signal to a reference sine wave generation circuit 23 which generates a reference sine wave vS. The circuit 23 subtracts a momentary voltage drop detection level value vl (e.g. vl=0.1 vSO)at a peak value vP from an official valve VSO of the input voltage VS, giving a waveform. An absolute value conversion circuit 24 output an absolute value ¦v2¦ of the sine wave V2 and an absolute value conversion circuit 25 outputs an absolute value ¦vS¦ of the voltage vS. A circuit 25 derives a difference of the absolute value (¦vS¦-¦2¦=DELTAv20) and an instantaneous voltage drop discriminator circuit 27 judges that a momentary voltage drop occurs if ¦vS¦

摘要： PROBLEM TO BE SOLVED: To provide an uninterruptible power supply for inhibiting drops in the load voltage, until a fast circuit breaker is turned off when a trouble occurs in a commercial power supply. SOLUTION: In the uninterruptible power supply 1, a bidirectional converter is linked on a steady basis, operated and reserved as a voltage source. A circuit having combined rectifier bridge and DC reactor is inserted so as to inhibit instantaneous drop, a voltage drop, when an interruption occurs and a regular voltage drop. Leakage impedance of a power distribution transformer is increased so as to increase the current-limiting reactor element, and the total reactance viewed from the linking point of the bidirectional converter to the power supply is increased. Since the voltage drop due to load power possibly becomes large, even though the effect for inhibiting voltage drop rate is high, if the leakage impedance of the power distribution transformer is large, the bidirectional converter controls reactive power and compensates the voltage drop, if the degree of the voltage drop is restricted.

解决方案：在不间断电源1中，双向转换器稳定连接，运行并保留为电压源。插入具有组合的整流桥和直流电抗器的电路，以便在发生中断和常规电压下降时阻止瞬时下降，电压降。配电变压器的泄漏阻抗增加，从而增加限流电抗器元件，从双向转换器的连接点到电源的总电抗增加。由于由于负载功率引起的电压降可能变大，所以即使抑制电压降率的效果高，如果配电变压器的漏电阻较大，则双向转换器控制无功功率并补偿电压降，如果压降程度受到限制。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce battery cost and increase the life of a battery by charging and discharging the battery by the operation of a system for only a prescribed period when electric power reaches its peak during a year, and conducting only stopping of the system or supplemental charging of the battery during other periods. SOLUTION: This electric power storing system is operated for only several days or weeks in the summer season when electric power reaches its peak to charge and discharge batteries 5, 8, and during other periods, stopped or controlled by such an operation as to conduct only supplemental charging for supplementing the self-discharging component of the batteries 5, 8. It is thus possible to reduce the number of yearly operation days of the system to reduce cycle life. It is also possible to increase the value of a discharging depth, and reduce required battery capacity for system capacity. Moreover, only general floating-charging amount or equivalent is used, thus it is possible to increase the life of the batteries 5, 8.

摘要： PROBLEM TO BE SOLVED: To cut contract demand without increasing battery capacity, by dividing load inside premises into a specific number of systems, normally feeding the load of the first system, feeding the load of the second system from a battery only at power peak time, and stopping feeding the load of the third system only at power peak time. SOLUTION: Divided into three systems, DC loads 3a to 3c, loads inside premises, are connected parallel to a rectifier 2. The first load 3a is normally fed from an AC power supply 1 via the rectifier 2, the second load 3b is fed from a battery 6 only at power peak time, and the feeding of the third load 3c is stopped only at the power peak time. With this structure, peak shift can be performed by supplying DC power at the power peak time to the second load from the battery 6 which had been charged at the time of low power rates. This peak shift combined with the simultaneous peak-cut by stopping feeding the third load 3c can cut contract demand without increasing the capacity of the battery 6.

SOLUTION: This circuit consists of a triangular wave generating circuit part 11 which generates an AC triangular wave signal (c) synchronized with an AC rectangular wave signal (u) to be controlled by integrating the AC rectangular wave signal (u) by an integrating circuit 13 and removing an obtained DC component by a low-pass filter 14; and a gain control circuit part 12 which passes the AC triangular wave signal (c) outputted from the triangular wave generating circuit part 11 through an absolute value circuit 15 and a low-pass filter 16 to calculate its rectification mean value (d), and which corrects the amplitude of the AC triangular wave signal (c) by using the ratio to the rectification mean value (x) at the time of a rate amplitude as a control gain (g) to output a synchronous triangular wave signal (v).
